I thought the Bible taught we were sinners by nature.
Sin lies only in hurting others unnecessarily. All other "sins" are invented nonsense.
Robert A. Heinlein, Time Enough for Love, 1973
The belief that humans are inherently evil is the most pernicious nonsense ever to dribble from the fevered minds of shamans.
Religious belief does not constitute scientific evidence, nor does it convey scientific knowledge.
